Abstract:
The effects of salinity and its three regulation ways on cell growth and EPA accumulation of Nannoxhloropsis oculata are investigated in this paper. It is found that 14.5‰~33.5‰ of salinity has little influence on the EPA content of N. oculata, but greatly affects the cell growth. The best range of the salinity for the cell growth and EPA accumulation of N. oculata was determined to be 27.0‰~29.0‰. Besides, similar effects on the cell growth and EPA accumulation are found with the salinities regulated by sea water and sea salt. However, using NaCl to regulate the salinity can not efficiently improve the cell growth and EPA accumulation.
